DETAILED DESCRIPTION

[0029] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0030] A lithium battery charger with dust removal function, such as Figure 1-Figure 5 As shown, it includes a shell 1, a shell 2, an exhaust fan 3, a blowing mechanism and a dust suction mechanism. The shell 2 is slidably connected to the shell 1, and the shell 2 can slide left and right on the shell 1. The shell 1 and the shell 2 constitute the lithium battery charger shell. A circuit board 100 is slidably connected in the shell 1. An exhaust fan 3 is installed on the left side of the shell 1. A circular opening is opened in the middle of the left side of the shell 1. The exhaust fan 3 is aligned with the circular opening. A plurality of heat dissipation holes are evenly opened on the shell 2. An air blowing mechanism for blowing away dust on the circuit board 100 inside the charger is provided between the shell 2 and the shell 1, and a dust suction mechanism for absorbing dust is provided on the shell 1.

[0031] like Figure 2-Figure 5 As shown, the blowing mechanism includes a reciprocating screw 41, a blowing frame 42, a belt drive group 43, a rotating shaft 44 and a splicing structure. The reciprocating screw 41 is rotatably connected to the top of the shell 2, and the blowing frame 42 is threadedly connected to the reciprocating screw 41. The blowing frame 42 is slidably connected to the shell 2, so that the rotation of the reciprocating screw 41 can drive the blowing frame 42 to reciprocate left and right through the thread. The upper left part of the shell 1 is rotatably connected to the rotating shaft 44, and a splicing structure is arranged between the rotating shaft 44 and the reciprocating screw 41. A belt drive group 43 is connected between the rotating shaft 44 and the main shaft of the exhaust fan 3, so that the belt drive group 43 can drive the rotating shaft 44 to rotate when the exhaust fan 3 is in operation.

[0032] like Figure 5 As shown, the splicing structure includes a triangular cone block 51, the triangular cone block 51 is connected to the left side of the reciprocating screw 41, and a conical groove 52 is opened on the right side of the rotating shaft 44. The triangular cone block 51 can be inserted into the conical groove 52 to realize the splicing between the rotating shaft 44 and the reciprocating screw 41, so that the reciprocating screw 41 can be driven to rotate when the rotating shaft 44 rotates.

[0033] like Figure 2-Figure 4As shown, the dust collection mechanism includes a dust collection frame 61, a collection frame 62, a connecting pipe 63, a cover plate 64, an air suction pipe 65 and an air pump 66. The dust collection frame 61 is connected to both the front and rear sides of the shell 1. The collecting frame 62 is connected to the bottom of the shell 1. The middle of the bottom of the shell 1 is open, and the open position is aligned with the collecting frame 62. The open part of the shell 1 is rotatably connected to the cover plate 64. There is damping between the cover plate 64 and the shell 1. When the cover plate 64 is closed, a closed space is formed between the collection frame 62. A plurality of connecting pipes 63 are evenly spaced and connected between the dust collection frame 61 and the collection frame 62. Two air pumps 66 are installed on the left side of the bottom of the shell 1. The air suction ends of the two air pumps 66 are connected to the collection frame 62 with air suction pipes 65. A screen is installed at the connection between the collection frame 62 and the air suction pipe 65 to prevent dust from entering the air suction pipe 65.

[0034] like Figure 2 and Figure 4 As shown, an exhaust pipe 67 is also included. The exhaust pipe 67 is connected between the air outlet end of the air pump 66 and the blowing frame 42. The exhaust pipe 67 runs through the shell 1 and is a folded hose.

[0035] When a lithium battery charger is needed, the present lithium battery charger can be used. When in use, the exhaust fan 3 can be started to exhaust for heat dissipation if heat dissipation is needed, and the heat dissipation holes can allow gas to enter, thereby promoting gas circulation and achieving the heat dissipation effect. During the heat dissipation process, the rotation of the main shaft on the exhaust fan 3 can drive the rotating shaft 44 to rotate through the belt transmission group 1 43, and the rotation of the rotating shaft 44 can drive the reciprocating screw rod 41 to rotate through the transmission of the triangular cone block 51, thereby driving the blowing frame 42 to reciprocate left and right. At the same time, the air pump 66 can be controlled to start, and the dust suction frame 61 generates suction through the transmission of the suction pipe 65, the collecting frame 62 and the connecting pipe 63. When the air pump 66 is started, its air outlet end can discharge the gas through the blowing frame 42 through the exhaust pipe 67, thereby blowing away the dust attached to the circuit board 100. At this time, the dust suction frame 61 is suctioning, and the blown dust can be sucked into the collecting frame 62 for collection. In this way, the effect of automatic dust removal can be achieved, and the operation is more convenient.

[0036] like Figure 6-Figure 8 As shown, a dust blocking mechanism is also included, which includes an inner pad 81, a middle ring 82, an outer ring 83 and an elastic member 84. The outer ring 83 is connected to the circular opening, the middle ring 82 is slidably connected to the outer ring 83, the inner pad 81 is slidably connected to the middle ring 82, and the elastic member 84 is connected between the inner pad 81 and the middle ring 82 and between the middle ring 82 and the outer ring 83. The elastic member 84 is a return spring.

[0037] When the exhaust fan 3 is in operation, the inner pad 81 and the middle ring 82 can be blown to move to the left, and the elastic member 84 is compressed, so that gaps are generated between the inner pad 81 and the middle ring 82 and between the middle ring 82 and the outer ring 83 for gas to be discharged. When the exhaust fan 3 stops operating, the inner pad 81 and the middle ring 82 are reset under the action of the elastic member 84, and the circular opening can be blocked to prevent dust from entering the outer casing of the lithium battery charger through the circular opening.

[0038] like Fig. 9 As shown, a cleaning mechanism is also included, which includes a connecting plate 91 and a sweeping brush 92. The connecting plate 91 is connected to the right side of the blowing frame 42, and a plurality of sweeping brushes 92 are evenly spaced and connected to the bottom of the connecting plate 91. The bottom of the sweeping brush 92 is in contact with the circuit board 100, so that the sweeping brush 92 can sweep away the dust attached to the circuit board 100 when moving.

[0039] like Fig. 9 As shown, it also includes side panels 101 and side brushes 102. The front and rear sides of the connecting plate 91 are connected to the side panels 101. A plurality of side brushes 102 are evenly spaced and connected to the side panels 101. The side brushes 102 on both sides are in contact with the dust collection frames 61 on both sides respectively, so that the side brushes 102 can sweep away the dust attached to the dust collection frames 61 when moving.

[0040] When the blowing frame 42 moves, the sweeping brush 92 and the side brush 102 can also be driven to move through the connecting plate 91 and the side plate 101. When the sweeping brush 92 moves, it can sweep away the dust attached to the circuit board 100 to prevent the dust from adhering to the circuit board 100, and when the side brush 102 moves, it can sweep away the dust attached to the dust suction frame 61 to prevent the dust from adhering and affecting the dust removal effect.

[0041] like Figure 7 As shown, it also includes a barrier frame 111 and a molecular sieve 112. The barrier frame 111 is connected to the right side of the shell 2. The barrier frame 111 is evenly spaced with through holes corresponding to the heat dissipation holes. The molecular sieve 112 is arranged in the barrier frame 111.

[0042] When air enters the heat dissipation hole, the hydrophilicity of the molecular sieve 112 can be utilized to dry the air passing through the molecular sieve 112 to prevent excessive dust and moisture in the air from sticking to the circuit board 100, making it difficult to brush off the dust on the circuit board 100.

[0043] like Fig.10As shown, a vibration mechanism is also included, which includes a connecting spring 121, a rotating shaft 122, a second belt transmission group 123 and a cam 124. A connecting spring 121 is connected between the circuit board 100 and the shell 1, and a rotating shaft 122 is rotatably connected to the lower part of the shell 1. A second belt transmission group 123 is connected between the rotating shaft 122 and the main shaft of the exhaust fan 3, so that the operation of the exhaust fan 3 can drive the rotating shaft 122 to rotate through the belt transmission group 123. A cam 124 is connected to the rotating shaft 122. The rotation of the cam 124 can resist the circuit board 100 and push the circuit board 100 to move, so that the circuit board 100 vibrates. When the exhaust fan 3 is operating, the rotating shaft 122 can be driven to rotate through the belt transmission group 123. When the rotating shaft 122 rotates, it can drive the cam 124 to rotate, so that the cam 124 repeatedly pushes the circuit board 100 to move, so that the circuit board 100 vibrates, and the connecting spring 121 can pull the circuit board 100 to reset after the circuit board 100 moves.

[0044] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
